transportation, but have to be separated.

4.1.4 Pipe bundles shall be securely fastened during transportation to avoid any move-

ment. Wooden blocks can be used for fastening purposes.

When several pipes bundles are stacked or not bundled pipes are stacked into several

ranks, pipe bundles and pipe ranks shall be separated by at least three wooden blocks, with the

thickness from 1.3780 to 1.5748 inch each, so that weight of upper pipe ranks is not distributed on-

to couplings of lower ranks.

4.1.5 When transported by sea, pipe bundles shall not be placed in water inside the ves-

sel’s hold or in any other corrosive environment. Dragging of bundles along the piles or hitting bun-

dles against hatches or rails is strictly forbidden.

5.4.2 Barite or metal brushes can cause scratches on surfaces of sealing elements result-

ing in loss of tightness.

5.4.3 After compound is removed, thread connections shall be purged with compressed

air or cleaned with dry rags.

5.4.4 When pipes are supplied with thread compound RUSMA-1 (з), RUSMA R-4 (з),

RUSMA R-14 (з) under thread protectors, it is allowed to perform the first running and pulling op-

eration with mill compound if mill thread protectors are screwed on and are not damaged. When

thread protectors are screwed off, it is necessary to make sure that:

– The compound is free of foreign particles (if there are foreign particles, compound shall

be removed according to 5.4.1, and reapplied according to 6.1);

– The compound is applied onto thread in an even layer (make the surface even and/or add

the compound of the same type if necessary);

of pipes (see Table 1):

- standard mandrel - if pipes and couplings do not have additional colourful marking.

- special mandrel - if one circular stripe of blue colour is applied on pins and couplings.

For drifting of pipes made of chromium and corrosion-resistant steels, polymer or aluminium

mandrels shall be used.

5.6.2 During drifting, the pipe shall be positioned in such a manner as to avoid sagging. If

any ropes or bars are used for the drifting process, they shall be clean. In case of freezing temper-

atures pipes shall be heated prior to drifting to remove snow and ice.

5.6.3 Pipe and drift shall be of the same temperature during drifting process.

5.6.4 Dimensions of the mandrels effective part shall comply with the ones specified in

Table 4 and in Table 5.

5.6.5 The mandrel shall pass through the entire pipe, when pulled manually without signif-

icant effort.

5.6.6 Pipes rejected during drifting process, shall be put aside until further decision on

5.8 Thread protectors installation 5.8.1 After inspection and control, thread protectors or caps shall be re-installed on pin

and coupling ends.

5.8.2 Before installation thread protectors shall be thoroughly cleaned and shall have no

significant damages, affecting protection of thread and seal against direct contact with exposure.


12

6 Make-up of pipes

6.1 Application of thread compound

6.1.1 To ensure optimum conditions for make-up and to avoid burrs of mating surfaces,

thread compound shall be applied on all the surfaces of thread, thread seals and thread shoulders

of pin and coupling.

The following types of thread compound are recommended: RUSMA-1 and its modifica-

tions, RUSMA R-4 and its modifications, RUSMA API Modified 1000, RUSMA API Modified,

Bestolife API Modified, Bestolife 72733, Bestolife 2000, Bestolife API Modified HP/HT, Bestolife

2000 NM, JET-LUBE API Modified.

During make-up of pipes from chromium steels with the chrome content over 3 %, it is rec-

ommended to use RUSMA R-4 and RUSMA R-14 thread compounds and their modifications.

By agreement with the developer of the connection, other thread compounds that meet re-

quirements of GOST R ISO 13678 and API RP 5A3/ISO 13678 are allowed.

6.1.2 Thread compound for make-up shall only be taken from original packages, delivered

by the supplier, the container shall show name, batch number and manufacturing date.

Compound from packages without proper identification shall never be used. It is prohibited to empty one package into another and to dilute the compound.

Compound applied shall be homogeneous, of ointment consistency, free from any solid in-

clusions (stones, sand, dry compound, fine chips, etc.).

Prior to use, check compound’s expiration date on the package.

Never apply compound with expired shelf life.

6.1.3 Make sure you follow the recommendations specified below when using thread

compound:

– Use the same compound (the same type) when assembling one casing string;

– Use a new compound package for each running, if the compound from opened package

is used, make sure it is free from foreign inclusions;

– Stir the compound thoroughly before use;

– Warm up the compound before application in case of freezing temperatures.

Compound shall be stored in closed overturned packages at the temperature specified by

the manufacturer. When storing partially unused compound, always specify the date of the first use

on the package.


13

6.1.4 Thread compound shall be applied in an even and continuous layer on the whole

thread surface, thread seals and thread shoulders of pins and couplings connections. Figures 2

and 3 demonstrate proper and improper application of compound.

Compound shall be applied only on thoroughly cleaned and dried surfaces of thread con-

nection.

Never use metal brushes for compound application!

Figure 2

Figure 3

6.1.5 Required amount of thread compound shall be distributed between coupling and pin

end as follows: two thirds shall be on the coupling end and one third shall be on the pin end.

Minimum and maximum compound mass mmin and mmax in gr for make-up of one thread

connection shall be calculated as follows:

mmin = 0.25 х D (2)

mmax = 0.30 х D (3)

where mmin is the minimum compound mass in gr rounded to an integral value;

mmax is the maximum compound mass in gr rounded to an integral value;

D is an outside diameter of pipes, in mm, rounded to an integral value.


14

Example – The minimum quantity of thread compound required for make-up of one thread connection of a coupling and pipe with an outside diameter of 244.48 mm (9 5/8 inch):

mmin = 0.25 х 244.5 61 gr (2.15oz) with at least 43 gr (1.52oz) per coupling and at least 18 gr

(0.63oz) per pin.

N o t e – calculated weight of compound is theoretical.

6.1.5 To determine the quantity of compound required for determined number of pipes, a

package of compound with specified volume shall be used.

Prior to pipes running down the hole, make sure that required thread compound of one type

is available.

6.1.6 Thread sealant can be used for make-up of pipes with crossovers or other string el-

ements provided the below conditions are followed:

- Shoulder torque of thread shoulders is from 25% of optimum make-up torque and final

make-up torque exceed shoulder torque by 20%;

– Shoulder torque of thread shoulders is higher than 80% of optimum make-up torque and it

does not result from thread jamming or damage, and 20% of optimum make-up torque is applied

after the shoulders interlock.

6.2 Running and pulling

6.2.1 Casing shall be assembled by a qualified personnel. Make-up of connection with the

use of torque registration system and make-up diagram plotting is the method ensuring proper

make-up and claimed by the manufacturer technical properties of the connection.

Methods of make-up inspection with the use of manometer of breakout tong, make-up tri-

angle (transverse stripe), make-up marks do not ensure proper make-up and can be used by the

user at his own and sole discretion without any guarantees on behalf of PAO “TMK” to get the

claimed by the manufacturer technical properties of the connection.

6.2.2 A special stab guide or bell guide is recommended for running and pulling opera-

tions (Figure 4). This device helps to align pin and coupling and prevent the connection from dam-

age.

6.2.3 In order to decrease the risk of new damages during running and pulling operations,

it is recommended to use pipe weight balancer.

In case of non-operating state of pipe weight balancer or its absence, a driller shall control

constant weight on hook (within limits ±220.46 lb) taking into consideration pipe weight.

6.2.4 While running a string of chrome steel pipes it is recommended to use an elevator

and special wedge claws to avoid pipe body damages.

6.2.5 Rotary tongs or casing make-up system shall be equipped with a speed governor and

shall ensure:

- at the initial stage - speed of make-up of not more than 2 rpm; safe entering of external

thread into internal thread (reverse is allowed).

- at the stage of the main make-up - smooth rotation of a pipe at the speed of not more

than 10 rpm;

- at the stage of rotation on shoulder - make-up speed of not more that 2 rpm and smooth

rotation of a pipe without jerks and stops.

If break-out of thread connection according to para. 6.5 and casing make-up system use

are required, rotary tongs shall be provided.

Figure 4

Rotary tongs shall be equipped with clamps for used pipe sizes to ensure adequate contact

area with the pipe body. Clamps diameter shall be 1 % greater than pipe nominal outside diameter.

Clamps shall be adjusted in such a way that they hold the pipe tightly and never slip.

For make-up and break-out of chromium steel pipes, the rotary tongs shall be equipped

with non-metallic or non-injurious tong dies.

Prior to make-up, tongs shall be positioned as per Figure 5.


16

Figure 5 6.2.6 Make-up equipment shall ensure torque at least 30 % greater than recommended

maximum make-up torque.

6.3 Assembly of string

6.3.1 Make sure thread protectors are secured in place prior to lifting pipes onto the rig

floor.

Lifting pipes to the rig floor without thread protectors or end caps is not allowed!

6.3.2 Prior to assembly of the string, remove thread protectors or end caps and check sur-

faces of thread seals and thread shoulders of the free pin for any mechanical damage according to

Figure 6.

Figure 6


17

6.3.3 During make-up process, if a derrick man is absent, it is required to control align-

ment of upper pipe coupling end (decline) with lower pipe rotation axis and correct the situation

timely by directing a driller accordingly (topdrive turn, elevator movements up and down, etc.)

(Figure 7).

Maximum misalignment of connected pipes shall not exceed 0.7874 inch.

6.3.4 Compound shall be applied according to para. 6.1. It is recommended to perform air

blasting of external and internal threads prior to compound application.

Figure 7

6.3.5 Make sure prior to make-up, that surfaces of thread, thread seals and thread shoul-

ders with applied compound are free from mud or mud laden fluid with small contaminations, hin-

dering tightness of connection. In case of mud or mud laden fluid on connection surfaces, clean

them and apply thread compound again.

6.3.6 When stabbing a pin into a coupling, pin end face shall not hit coupling end face, pin

sliding down into the coupling is not allowed.

6.3.7 The make-up torque for a thread connection shall be within the range from the min-

imum up to the maximum torques, specified in Table 7 for the corresponding size of pipes and

grades taking into consideration additional colourful marking (see Table 1).

If thread connection make-up with torque within the limits shown in Table 7 is not in compli-

ance with specified requirements, Мopt can be corrected but not more than by ±15 % (for pipes

with outside diameter of 4 inch not more than than by ±10 % ). At that, the values of Мmin and

Мmax shall be corrected but not more than by ±10 % of corrected Мопт.

6.3.8 During make up of pipes and couplings made of steels of different grades, the

make-up torque value shall be chosen according to the lowest steel grade of both pipe and cou-

pling.

6.3.9 Make-up of pipes and couplings shall be performed with the use of make-up regis-

tering equipment, by make-up diagrams, at that it shall meet the requirements specified in

Annex A.

Make-up without equipment for make-up registration is performed for pipes with the outside

diameter of 4 inch using make-up torques and make-up triangle applied by the manufacturer on

free ends of pipe, coupling (Figure 8a).

Make-up of pipes with the outside diameter of 4 1/2 inch up to 13 5/8 inch is performed us-

ing make-up marks (in light paint) applied by the manufacturer on free ends of pipe, coupling and

the make-up triangle on a pipe (Figure 8b).

Transverse stripe can be applied (in light paint) on pipe instead of make-up triangle.

Figure 8

6.3.10 At the initial stage of assembling it is recommended to perform the first two revolu-

tions of pipe using strap tongs (chain tongs are allowed for use only with the safe gasket which is

set between the pipe body and the tong thus avoiding pipe body damage) to assure connection of

external and internal threads, i.e. entering of external thread profile in mating profile of internal

thread.

At this stage pipe reversal half-revolution is allowed for steady continuation of make-up

without threads overlapping and high-quality assembly.

6.3.11 When making-up chromium steels pipes, the first two turns shall be carried out

manually, or strap tongs can be used (Figure 9). Chain tong is allowed for use only under condition

that the pipe body is secured from damage (e.g. by the safe gasket which is set between the pipe

body and the tong).

Figure 9

6.3.12 Make-up rotation speed during connection make-up with the rotary tong shall corre-

spond to the values specified in Table 8.

Table 8 – Rotation speed during make-up Start of make-up Make-up completion

(rotation on shoulder) First two turns Further turns Speed maximum

2 rpm, Better manually

Speed maximum 10 rpm

Speed maximum 2 rpm

6.3.13 Even longitudinal movement of the pipe resulting from gradual increase of number

of engaged revolutions shall be watched, significant warming of the connection (not more than

1220F of the ambient temperature) shall not be allowed.

6.3.14 Make-up shall not cause significant mechanical damages like galling, jamming or

other imperfections on pipe and coupling body.

The outer surface of coupling shall be free of damages with the depth larger than 0.5% of the

coupling nominal outside diameter.

Damages from tong clamps are allowed on the pipe outer surface provided that the actual

pipe wall thickness, taking into account depth of the damage, shall be not less than 87.5 % of the

nominal pipe wall thickness.

After make-up of chromium steel pipes, the trace depth on the pipe body shall be not more

than 0.0079 inch.


22

6.3.15 When using hydro tongs with back up, the following conditions shall be observed:

During the first rotations (better manually, using a chain tong), back up shall be opened,

and make-up shall be performed without make-up torque increase. At that it is possible to make

horizontal movements of hydro tongs (right/left) to prevent thread bite during make-up.

Upon increase of make-up torque (on the last 3 turns), it is required to stop, fix the back up

on lower pipe body and continue make-up.

6.3.16 When the value of the final make-up torque equal to Мmax value is achieved, turning

of coupling from the side of mill connection is allowed, if the make-up diagram has not been

changed (Figure 10). The final make-up torque values shall be within Мmin to Мopt limits in order to

reduce the probability of turning.

6.4 Make-up inspection by the make-up diagram

6.4.1 General provisions

6.4.1.1 The shoulder torque Мsh of thread shoulders (box shoulder and pin shoulder) shall

be within the range between 5% and 80% of the optimum make-up torque Мopt.

6.4.1.2 The final make-up torque shall be within the range from the minimum Mmin to the

maximum Мmax make-up torques.

6.4.1.3 Typical cases of make-up diagram shape non-compliance are shown in

Figures 11 – 15.

6.4.1.4 If the make-up curve is of improper shape, giving rise to doubt in make-up quality,

break out the connection.

After break-out the surface of pin and coupling thread connections shall be cleaned from

compound and visually inspected.

If no surface damages and (or) shape distortion (decrease of pin or box shoulder inside di-

ameter, sagging on coupling inside surface) are observed, thread compound shall be applied on

thread connections of pins and couplings again in accordance with the requirements of 6.1, the

settings of equipment, alignment of made-up pipes shall be checked, make sure there is no slip-

page of clamp jaws and make-up the connection again.

If surface damages are observed and can be repaired in accordance with para 6.5.9. after

repair thread compound shall be applied on pin and coupling connections in accordance with the

requirements of para 6.1,


23

the settings of equipment, alignment of made-up pipes shall be checked, make sure there is

no slippage of clamp jaws and make-up the connection again.

If the damages observed cannot be repaired it is necessary to reject the connection.

If the shape of the make-up diagram after re-make-up is similar to the shape of the first

make-up diagram, the pipe shall be laid aside and make-up with another pipe shall be performed.

The laid aside pipe is allowed to be used for further make-up if no damages are observed or the

damages are repaired. Reapply thread compound of the appropriate type and quality, check the

settings of equipment.

Pipes on which pin or coupling were made up three times with replacement of counter pipe

and with make-up diagrams of a wrong form shall be rejected.

6.4.2 Correct make-up diagram

6.4.2.1 If make-up is performed correctly and all the thread connection geometric parame-

ters comply with the established requirements, the make-up diagram clearly shows defined areas,

which correspond to torque increase due to mating of thread surfaces (area I), thread and sealing

element (section II), thread, sealing and shoulder elements (area III).

6.4.2.2 The torque increase on the first revolutions of make-up corresponding to the initial

mating of thread shall be smooth and even. Torque shall increase upon further mating of thread

and mating of sealing elements. The moment of shouldering is followed by sharp increase of

torque thus confirming correct process of make-up. Value of torque increase from the moment of

the connection shouldering shall be at least 1000 Nm per 0.015 of rotation.

24

6.4.2.3 Depending on the rotary tong used, its adjustment, and other factors, the make-up

diagram (especially in area I) can show areas with insignificant deviations from the straight line:

oscillations, leaps, etc. Such deviations shall be deemed acceptable, provided that peak values

and shoulder torque Msh value are not exceeded, and it is possible to track areas of mating of

thread surfaces, seals and shoulders on the diagram.

6.4.3 Make-up diagram when torque increase stops

If at the final step of make-up procedure torque increase stops and there appears a hori-

zontal area (area IV, Figure 11), but no slippage of clamp jaws is observed, actions shall be taken

according to para 6.4.1.4.

Figure 11

6.4.4 Make-up diagram when torque is low

Too low value of shoulder torque (Msh) (below 5% of Mopt) on the make-up diagram

(Figure 12) may result from:

- Application of wrong type of compound;

- Compound contamination or its poor storage conditions;

- Defects of load sensor.


25

Figure 12 If the make-up curve is of improper shape, the following actions shall be taken according to

para 6.4.1.4.

6.4.5 Make-up diagram when torque is high

Too high value of shoulder torque (Msh) (over 80% of Mopt) on the make-up diagram

(Figure 13) may result from:

- Damage of thread and/or thread seals;

- Improper thread cleaning;

- Application of wrong type of compound;

- Thread compound contamination or high density of thread compound (for example, at low

temperatures);

- Defects of load sensor.

Figure 13

If the make-up curve is of improper shape, the following actions shall be taken according to

para 6.4.1.4.


26

6.4.6 Make-up diagram with torque leaps

Torque leaps on the make-up diagram (Figure 14) may result from:

- Uneven application of thread compound;

- Misalignment of coupling make-up equipment;

- Insufficient force of rotation on shoulder;

- Slippage of clamp jaws.

Such a diagram is considered good and may be accepted according to requirements speci-

fied in para. 6.4.2.3.

In case of any doubts concerning the make-up quality, the following actions shall be taken


6.4.7 Make-up diagram with a wave-like effect

Make-up curve with a wave-like effect (Figure 15), may result from:

- Improper thread cleaning;

- Thread compound contamination or high density of thread compound (e.g. at low tem-

peratures);

- Excess of compound.


27

Figure 15 Such a diagram is considered good and may be accepted according to requirements speci-

fied in para. 6.4.2.4.

In case of any doubts concerning the make-up quality, the following actions shall be taken


6.5 Break-out of string

6.5.1 When the string is being pulled out of the well, pin end faces are not allowed to hit

against coupling end faces.

6.5.2 Even longitudinal movement of the pipe resulted from gradual increase of number of

turns of thread run-out, shall be watched when the connection is broken-out.

A driller fixes the weight on a hook load free, provides tension within 220.5÷330.7 lbs, and

tries to maintain these values in the process of breaking-out. On the last turn pipe moving up shall

be stopped in order to fix thread run-out (a click) and after that the pin shall be moved out of the

coupling.

6.5.3 Prior to break-out, the rotary tongs shall be positioned as per Figure 5.

6.5.4 Break-out torque shall provide for the connection disassembly.

Reduce of thread connection break-out torque by 20% relative to the recommended opti-

mum make-up torque Mopt is allowed.

6.5.5 Speed of connection break-out by rotary tong shall correspond to the speed, speci-

fied in Table 9.

6.5.6 Make-up shall not cause significant mechanical damages like galling, jamming or

other defects on pipes and couplings body.

The outer surface of couplings shall be free of damages with the depth larger than 0.5% of

the couplings nominal outside diameter.

Damages from tong clamps are allowed on the pipe outer surface provided that the actual

pipe wall thickness, taking into account depth of the damage, shall be not less than 87.5% of the

nominal pipe wall thickness, the damage depth on the outer surface of pipes from chromium and

corrosion-resistant steels shall be not more than 0.0079 inch.

6.5.6);

– Cleaning of external and internal thread connections from compound and contaminations

(ref. para. 5.4);

- Visual inspection of thread, seal and thread shoulders surface of pins and couplings

thread connections (see 6.5.9). In case of any damages detection perform the corresponding re-

pair or reject the pipes and couplings;

6.6 Make-up inspection by make-up triangle

6.6.1 When making-up thread connection by make-up marks, superimposition of the mark

on the coupling with the first mark on the pin in the direction of make-up, corresponds to shoulder

of pin and box shoulders. [Figure 18 а)]

6.6.2 When make-up torque value is reached a make-up mark on the coupling shall coin-

cide with the second mark on the pin in the direction of make-up or be positioned between the first

and the second marks that corresponds to rotation on shoulder of thread connection intended to

reach given diametrical interferences in thread and radial seal as well as to engage thread shoul-

ders in seal process. [Figure 18 b), c)]

Rotation on shoulder is accompanied by significant torque increase; herewith it shall be

minimum 90 % and maximum 110 % of optimum make-up torque value.

6.6.3 When make-up torque value is reached, coupling end face shall align with the base

of make-up triangle (transverse stripe) on the pin with allowable deviation ± 0.0394 inch.

6.6.4 Various locations of make-up marks after thread connection make-up with optimum

torque and corresponding to such make-up mating of thread shoulder surfaces are possible (Fig-

ure 18).


31

Figure 18, а) – the connection is under-torqued. The mark on coupling does not run up to

the first mark on pin in the direction of make-up. It means that there is a gap between the mating

surfaces of pin and coupling. Make-up is allowed to be continued till the mark on coupling aligns

with the first or the second mark on pin in the direction of make-up [Figure 18 b), c), d)]. The make-

up torque should not exceed its maximum value.

If the make-up torque exceeds its maximum value, and the mark on coupling doesn’t reach

the first mark on pin in the direction of make-up, the connection shall be broken-out, cleaned from

compound, surfaces of pin and coupling connections shall be visually inspected.

In case of damages which cannot be repaired by the methods listed in Table 10, the thread

connection shall be rejected.

If no visible damages are observed on the thread connection or the damages can be re-

paired, upon elimination of damages the connection can be made-up again, herewith the total

number of make-ups shall be not more than three times.

When performing remake-up, the mark on coupling shall stay between the first and the se-

cond marks on pin or it may align with the second mark on pin [Figure 18 c), d)]. The torque shall

be within the range from the optimum to the maximum value.

When make-up is complete, inspection of make-up correctness shall be performed accord-

ing to the position of make-up triangle.

Figure 18, b), c), d) – the connection is correctly made-up with the minimum rotation on

shoulder [Figure 18 b)], with optimum rotation on shoulder [Figure 18, c)], with the maximum rota-

tion on shoulder [Figure 18, d)].

Inspection of make-up correctness shall be performed according to the position of make-up

triangle.

Figure 18, e) – the connection is over-torqued. The mark on coupling is located behind the

second mark on pin, that means possible deformation of mating pin and coupling seal surfaces.

In this case the coupling location shall be inspected relative to make-up triangle.

If the coupling end face aligns with the make-up triangle base and the mark on coupling is

located behind the second mark on pin at the distance of not more than 0.4724 inch [Figure 18, e)],

the connection can be accepted.

If the coupling end face aligns with the make-up triangle base, but the mark on coupling is

located behind the second mark on pin at the distance of more than 0.4724 inch [Figure 18, e)], the

connection shall be broken-out and inspected. The thread connection shall be rejected if defor-

mation of pin and coupling seal surfaces is observed and shall be remade-up with optimum torque

if no deformation is observed.
